MEDIK8 is a British science-led skincare brand founded in 2009 by physiologist and pharmacologist Elliot Isaacs. At the heart of its approach is the CSA® philosophy, which simplifies effective age prevention into three evidence-based pillars.

Vitamin C in the morning provides antioxidant support, sunscreen limits photodamage, and vitamin A in the evening regulates skin renewal and corrects existing signs of ageing.

MEDIK8 has particular expertise in retinoids. For its Crystal Retinal range, the brand developed a patented retinal stabilisation system and a progressive ladder of concentrations, allowing the intensity of skincare to be gradually increased as the skin adapts.
